Description

Technical Field

[0001] This utility model relates to the field of measurement technology, and in particular to a fully automatic go / no-go gauge testing device. Background Technology

[0002] A go / no-go gauge is a precision measuring tool used to quickly determine whether the dimensions of a workpiece are within the specified tolerance range. It is a type of limit gauge and is widely used in machining, parts manufacturing and other fields.

[0003] When using fully automatic go / no-go gauges, the material is typically fed automatically. Some equipment on the market uses vibration feeding, which involves connecting a vibrating feed rail to a fixture (carrier), and the material is fed into the fixture by the vibration of the feed rail. This design, which uses vibration feeding, cannot completely guarantee that the material will quickly enter the fixture, and the material may fall out of the fixture when switching fixtures.

[0004] For example, Chinese patent application number CN202221468283.9 discloses an integrated automatic thread inspection machine, specifically stating that "the feeding station includes a vibratory feeder and a direct vibratory feeder. One end of the direct vibratory feeder is connected to the outlet of the vibratory feeder, and the other end is close to the workpiece fixture. When the feeding station is working, the vibratory feeder moves the workpiece to be inspected onto the direct vibratory feeder, and the direct vibratory feeder moves the workpiece to be inspected onto the workpiece fixture, completing the feeding action." This design, which uses vibration feeding, cannot completely guarantee that the material will quickly enter the fixture. Furthermore, when switching fixtures, the material may fall out of the fixture. Utility Model Content

[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] Please refer to Figures 1 to 7 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a fully automatic go / no-go gauge testing device.

[0029] The vibrating feed rail 32 delivers the material 29 to the feeding seat 35, which pushes the material 29 to the feeding channel 38 on the loading seat 37, so that the material 29 falls from the feeding channel 38 into the fixture 22. The material 29 can fall into the fixture 22 quickly and will not fall off, resulting in a high loading success rate.

[0030] This application provides a fully automatic go / no-go gauge inspection device, including a turntable mechanism 20, and a feeding mechanism 30, a go gauge inspection mechanism 40, a no-go gauge inspection mechanism 50, and a discharging mechanism 60 disposed on the side of the turntable mechanism 20; the turntable mechanism 20 includes a turntable 21 and a fixture 22 disposed on the turntable 21; the feeding mechanism 30 includes a vibrating material rail 32, a feeding seat 35 connected to the discharge end of the vibrating material rail 32, and a feeding seat 37 disposed on the movement trajectory of the feeding seat 35; the feeding seat 35 is provided with a material port 36; the feeding seat 37 is provided with a feeding channel 38; the feeding seat 35 and the feeding seat 37 are closed together, and the material in the material port 36 falls from the feeding channel 38 into the fixture 22.

[0031] The turntable 21 is equipped with several fixtures 22, which are used to load materials. During operation, the feeding mechanism 30 loads the materials into the fixtures 22, and then performs go gauge and no-go gauge checks. After the checks are completed, the materials are sorted and unloaded. This design realizes fully automatic feeding, unloading, checking, sorting and unloading.

[0032] During feeding, the material in the vibrating feed pan 31 is conveyed by the vibrating feed rail 32. The vibrating feed rail 32 delivers the material to the feeding seat 35. Then the feeding seat 35 pushes the material to the feeding channel 38 on the feeding seat 37. Under the action of gravity, the material falls from the feeding channel 38 into the fixture 22. Therefore, this design can ensure that the material falls into the fixture 22 quickly and will not fall out, resulting in a high feeding success rate.

Under the action of gravity, the material falls into the fixture 22. The first detection hole 39 and the first sensor 310 work together to detect whether there is material in the feeder 35 and whether the material has fallen into the feed channel 38. This ingenious design structure results in higher detection accuracy. The second sensor 311 faces the fixture 22 and can detect whether there is material on the fixture 22.

Preferably, the bottom of the material hole 25 is small to prevent material from falling out. When material needs to be discharged, the material needle 28 pushes the material in the material hole 25, and the material falls down. This design is simple and ingenious.
